FOUNTAIN-PEN.

Application filed November 20, 1915.

To all ywhom it may concern.'

Be. it known that I, FRANK H. lvIooNnYa a citizen of the United States,and a resident of Hinsdale, in the county of Dupage and State ofIllinois, have invented a certain new and useful Fountain-Pen; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention. such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

j This invention relates to fountain pens of the class in which the inkreservoir comprises a. compressible tube. the expansion of which fromcompressed position draws in a supply of ink with w-hich the inlet endof the tube may have communication.

The object of my .invention is the provision of improved simple andefficient control means for the compressor bag of fountain pens, whichmeans is also operable to lock the compressor bar against compressingmovement.

A further object of my invention is the provision of a compressor barcontrol means Vof this character. which is carried entirely by thecompressor bar and is capable of being easily and quickly "placed inoperative relation to or removed from the pen barrel together with thecompressor bar. thereby providing a simple assembling proposition forpens of the class described. .Further objects and advantages of theinvention will be apparent .from the followingl detailed descriptionthereof.

lVhile the invention in its broader aspect is capable of embodiment innumerous forms, a preferred and one slightly modified form thereof areillustrated in the ,accompanying drawings, in which,`

ver thereof in unlocked or compressing position and with parts of thecompressor bai broken away.

and Fig. G is a cross-section of a slightly modified form of controlmeans.

Referring to the drawing the compressor bar and its s. l designates theusual barrel or casing of a fountain pen.

2 the pen point holding` men iber. and 3 the ink reservoir, which iscarried by the member Q ture, such, for instance, as

Disposed within the bairel l the tube 3 and in contact compressor bar 4,of the tube and transversely pressing of the tube 3 for and is usuallyof a coinpressible naa rubber tube. at one side of therewith is a whichextends lengthwise is adapted to be moved of the barrel to effect acoina greater portion Iof its length to eject air therefrom. so thatasubsequent expansion of the tube will draw a supply of ink into thereservoir or tube through the member 2. in the art.

The control means for the as is well understood compressor bar t, inwhich the pieseiit invention resides.

comprises a block 5 and lever member G. the

former being carried by the compressor bar 4 at the outer side thereofbeing pivotally carried by the block and the latter For convenience ofconstruction the compressor bar 4 and block 5 pieces, which are rigidlyse in any suitable manner, as f the projecting of a side of the block 5opening in the bar il. said l are made in separate cured together orinstance, by

lug T from the under through a registering ug being' upset at its outerend or provided with other suitable means for from the bar opening.

The block 5 is narrow in length extending lengthwise of the bar J-preventingits withdrawal width with its and is adapted to projectoutward from 'the interior of the barrel through slot or opening` 8 inthe side a registering wall thereof.

the block being of suitable length to project at its outer end a shortouter side of distance beyond the the barrel when the bar L is againstthe adjacent side of the barrel or is in restricted position with lreservoir 3, as shown in Figs The lever member 6 of the cont-rol meansis of bowed the present instance, with provided with axially registpivot-studs 9, 9, which are ii respect to the 2 and 4. compressor bar orbail form, in the ends thereof crineinturned itended to pivotally engagewithin bearing recesses in the .respective ends of the portion of theblock .entirely through the outer end portion of the block lengthwisethereof, as shown in Figs. 2 and 3. The bowed lever member 6 ispreferably of a spring nature to adapt the ends thereof to spring intothe respective bearing recesses of the block, thereby enabling the levermember to be easily and quickly engaged with or removed from the block 5by an outward springing of the end portions of the lever member for suchpurpose.

The bar 5 is provided at each end thereof in radial relation to theopening 10 with two seats 11 and 12 in which the respective end portionof the lever member 6 respectively springs when in upright or recliningposition with respect to the block 5, as best shown in Fig. 5. It isapparent that when the lever member 6 is in upright position the springtendency thereof will cause its ends to spring into the respective seats11 provided therefor in the block 5, thereby yieldingly retaining thelever member in such position, and that the ends of the lever member,when moved to reclining or transversely projecting position with respectto the block 5, spring into the registering seats or depressions 12 andyieldingly retain the lever member in such reclining position. When thelever 6 is placed in its reclining position, which may'also be termedits locking position, it rests in a registering surface groove or seat13 provided therefor in the outer surface of the barrel 1, thuspreventing the entire width of the lever, when in such position, fromprojecting outwardV beyond the surface of the barrel '1. This alsoreduces the distance of projection" of the block 5 without Vthe barrel.Y 1

ln Fig. 6 the lever carrying block, instead of being formed in asingle'piece, comprises a strip of sheet metal 15, which is of invertedU-form withV its legs projecting through registering openings in thecompressor bar t and having the filler block or piece 16 insert- Y edtherebetween without the compressor bar site ends and coperating withthe looped end of the part 15 toform bearing openings at yoppoof theblock for receiving the respective bearing member lt will beunderstoodthat this V"is only one of numerous modifications whichV may be made ofthe leverjcarrying'block 5 shown in the other figures of the drawing.

It is also evidentthat the lever member 6 may be varied in form and inits manner of attaching` to Vthe block 5 withoutl departing fro'i'nthe`spirit of the invention, the form being merely illustrative of oneembodiment thereof.

to the block 5, which latter in its block ends.

studs' 8 of the bowed lever It will be understood from the abovedescription that to operate the compressor bar et to eect a filling ofthe tube or reservoir 3 the member iirst unlocks the compressor bar bymoving the lever 6 from its reclining position shown .in Figs. 1 and flto the upright position shown in Figs. 2, 3 and 5. The operator thenpresses inward on' the outer end of the lever, thereby causing it toenter the barrel opening 8 Vand to force the block 5 and compressor bara inward to effect a complete compression of the reservoir tubeV 3. Thishaving been done the pressure lever is relieved of the inward forcingpressuie,`thei'eby permitting the compressor bar, block 5 and lever 6 tomove outward to their normal extended positions by the expanding andfilling action of the reservoir 3, as is well understood in the art. Thecompressor bar is now locked in its normal raised position by swingingthe lever 6 from its upright to its reclining position with respectposition it yieldby reason of the lever ends the seats 12 providedtherefor As the lever 6 isswungl from its upright to its reclining orlocking position the inner` end portion vof the leverVV will havebearing or fulcruin contact with the marginal edge wall of the opening 8over which it is swung and will thereby eX- ert an outward pullingorleverage pressure on the block 5 to draw it and the compressor bar 4outward to the full limit of their move- Vments so that the compressorbar 4 and its attached parts are not only held against free or rattlingmovements within' the barrel, but the reservoir 3 is relieved of thepressure of the bar thereon which might be present if the bar were freeto have limited transverse movements within the barrel when in lockedposition.

VIt isevident that the control meanswhich I have provided for thepressure bar enablesthe parts to be easily and quickly as-Vsembledwithout pivoting or attaching any part to the pen barrel, as itis only necessary to insert the compressor bar l and the block 5 carriedthereby into the barrel 1 through ingly retains springing into Ythe'open end thereof, project the block 5 outward through theV barrel slotor opening 8 and then place the lever memberl into engagement with theprojected endv of the block. Y

While I have herein shown and described a specific embodiment of myinvention for illustrative purposes,'and have disclosed and discussed indetail the construction and arrangementincident to'one applicationthereof, it is to be understood that the inventionf is not limited tothe mere detail or relative sev iio

arrangement of the parts, but that devia- Y tions from ltheillustratedform or. embodi-v ment ofy the invention may be made withoutA,V

departing froni'the spirit of the'claims."V

which are spaced lengthwise of the barrel,

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is,-

l. In a fountain pen, a barrel having an opening in a side thereof, areservoir compressor bar having a part projecting from the outer sidethereof, and a bowed form of lever having its ends in pivotallongitudinal spring engagement with said part and operable from withoutthe barrel to exert an inward reservoir compressing movement to saidpart and bar and being movable relative to the bar and barrel to coactwith the latter to lock the bar in normal position.

2. In a fountain pen, a barrel having an opening in a side thereof, areservoir compressor bar disposed in said barrel and having a part forprojecting into said opening, said part having axially alined bearingsand a bail-like member having` releasable spring engagement with saidbearings for pivotal movements transversely of the barrel and operableto impart reservoir compressing' movement to said bar or to lock the barin one position of its movement.

3. In a fountain pen, a barrel having an opening in its side wall, areservoir compressor bar disposed within the barrel and having a partprojecting outward therefrom and into said opening, said part beingelongated in form lengthwise of the barrel and having its outer endportion provided with axially registering bearing sockets which arespaced lengthwise of the barrel, and a bowed form of control leverhaving its ends provided with pivot studs which are sprung into saidsockets, said lever being operable to impart a compressing movement tosaid bar from without the barrel and to coact with the barrel to lockthe bar in inoperative position.

In testimony whereof, I have hereunto signed my name to thisspecification.
